[Qemu-devel] [PULL 8/8] configure: unset interfering variables

Subject: [Qemu-devel] [PULL 8/8] configure: unset interfering variables

From: Cornelia Huck <address@hidden>

The check for big or little endianness relies on grep reporting
match/non-match on the generated binary. If the user specified
--binary-files=without-match in their GREP_OPTIONS, this will fail.

Let's follow what autoconf does and unset GREP_OPTIONS and CLICOLOR_FORCE
at the beginning of the script.
